Human papillomavirus (HPV) vaccines offer primary prevention of cervical cancer and protection against other HPV-associated cancers. HPV vaccine coverage in the United States (U.S.) remains low, particularly among older adolescents/young adults, and the uninsured. We assessed awareness and knowledge of HPV disease, HPV-related cancers, and HPV vaccines among working, uninsured adults. Data from the 2014 Health Information National Trends Survey (HINTS 4, Cycle 4) were used as a benchmark. Patients were surveyed in late 2014 at the Volunteers in Medicine free clinic in Duval County, Florida...

Prevention of cervical cancer has been unsuccessful in Japan because of low rates of cancer screening and vaccination. The Vaccine Adverse Review Committee of the Japanese Government investigated 2,475 adverse events and reported 617 (6.9/100,000) severe cases and 176 (2.0/100,000) cases with chronic pain. The proactive recommendation for human papillomavirus (HPV) vaccination has been suspended since June 2013. In this study, we examined vaccination rate and incidence of abnormal cervical cytology in women aged 20 to 24 years attending cancer screening in Miyagi...

BACKGROUND: Human papillomavirus vaccination may result in lowered intention to be screened for cervical cancer, potentially leading to gaps in screening coverage and avoidable cervical cancer diagnoses. OBJECTIVE: To examine the association between human papillomavirus vaccination and subsequent cervical cancer screening initiation and adherence to recommended screening intervals to detect gaps in screening coverage and inform future prevention efforts. STUDY DESIGN: A retrospective cohort study was conducted in two distinct cohorts of female members of Kaiser Permanente Southern California, a large integrated healthcare delivery system...

BACKGROUND:  Uptake of the human papillomavirus (HPV) vaccine in the United States is slow, and the real-world effectiveness of the vaccine has not been assessed in high-risk adolescent populations. METHODS:  We conducted a longitudinal study of 1139 sexually-active, inner-city adolescent women receiving the 3-dose quadrivalent (4vHPV) vaccine. Cervical and anal specimens collected semi-annually were tested using a L1-PCR assay. Post-vaccination incidence of 4vHPV vaccine and non-vaccine HPV types, and risk of cervical cytological abnormalities, were assessed in relation to time-to-completion of all three vaccine doses...

BACKGROUND: Cervical cancer is the greatest cause of age-weighted years of life lost in the developing world. Human papillomavirus (HPV) infection is associated with a high proportion of cervical cancers, and HPV vaccination may help to reduce the incidence of cancer. The aim of the study was to identify barriers, obstacles, and strategies and to analyze key concerns and lessons learned with respect to the implementation of HPV vaccination program in low- and middle-income countries. METHODS: The Gardasil Access Program (GAP) is a donation program established to enable organizations and institutions in eligible low-resource countries to gain operational experience designing and implementing HPV vaccination programs...

Human papillomavirus (HPV)-associated squamous cell carcinoma of the oropharynx is a well-defined entity mostly affecting young to middle-aged male non-smokers. It is generally associated with a favourable outcome, and for this reason a less intensive therapeutic approach has been proposed for this subset of patients. The incidence of HPV-associated oropharyngeal cancers is rapidly increasing in most Western countries, but detailed epidemiological data are not available for the Italian population. Furthermore, among other head and neck regions, a smaller proportion of oral high-grade dysplasia and cancers seems to depend on HPV infection, whereas its role in laryngeal cancer is recognised as less relevant...

Current sources of publicly available human papillomavirus (HPV) information may not adequately meet the needs of diverse families. This study sought to describe associations between sociodemographic and acculturation factors, and sources of HPV information among diverse parents and caregivers. Community organizations purposively recruited participants from African American, African refugee, Hispanic/Latino, American Indian, and Native Hawaiian and Pacific Islander communities for a 21-item survey (N = 228)...

Numerous types of human papillomaviruses (HPVs) have been identified, and the global burden of diseases associated with HPV infection is remarkable, especially in developing regions. Thus a low-cost broad-spectrum prophylactic vaccine is urgently needed. The N-terminal amino acid 17-36 of HPV 16 L2 protein is confirmed to be a major cross-neutralizing epitope (RG-1 epitope). Monomeric proteins containing RG-1 epitopes and scaffold proteins, such as bacterial thioredoxin or modified IgG1 Fc fragment and L2 epitope fusion protein, induced cross-neutralizing antibodies, arousing the possibility of the development of low-cost monomeric vaccine in bacterial expression system...

BACKGROUND: Primary care physicians (PCPs) play a key role regarding vaccination in France. The aims of the present study were to define the scoring rules and to assess the measurement properties of the 'Determinants of Intentions to Vaccinate' (DIVA(©)) questionnaire that aims to assess PCPs' attitudes and beliefs toward vaccination. METHODS: The DIVA questionnaire was derived from a literature review and PCPs focus groups. Scoring and early validation of the DIVA questionnaire were determined during a cross-sectional study conducted in France...

Human papillomavirus (HPV) vaccine coverage remains low in the USA. The Society for Behavioral Medicine (SBM) supports the goals outlined by Healthy People 2020, the President's Cancer Panel, and the National Vaccine Advisory Committee to increase vaccination coverage among both males and females. SBM makes the following recommendations in support of efforts to reduce structural and other barriers to HPV vaccination services in order to increase rates of series completion. We encourage legislators and other policymakers to improve administration authority, insurance coverage, and reimbursement rates to healthcare providers who make the HPV vaccine available to adolescents; provide instrumental support to fund the development of school curricula on HPV vaccination; and increase public awareness that HPV vaccination can prevent cancer...

Penile cancer is a rare and devastating disease, especially at advanced stages. The etiology of penile cancer is multifactorial with multiple established risk factors including infection with the human papillomavirus (HPV). Approximately 40% of penile cancers are attributable to HPV, although the literature describing HPV as a prognostic factor is mixed. The pathogenesis of HPV infection as well as vaccination practices may provide valuable therapeutic agents to treat this rare and difficult disease.

BACKGROUND: Cervical cancer is associated with infection by certain subtypes of human papillomavirus (HPV). The L1 protein comprising HPV vaccine formulations elicits high-titre neutralizing antibodies and confers protection against specific HPV subtypes. HPV L2 protein is an attractive candidate for cross-protective vaccines. HPV-33 and HPV-58 are very prevalent among Chinese women. METHODS: To study the gene intratypic variations and polymorphisms of HPV-33 and HPV-58 L1/L2 in Sichuan China, HPV-33 and HPV-58 L1 and L2 genes were sequenced and compared with other genes submitted to GenBank...

Human papillomavirus (HPV) vaccination is safe and effective in preventing anogenital cancers and warts. However, myths have surrounded the HPV vaccine since its approval, including the possibility that HPV vaccinated young people are more likely to engage in risky sexual behaviors. The purpose of this study was to assess the association between HPV vaccination and engaging in inconsistent condom use in a sample of U.S. college students. A secondary data analysis of the National College Health Assessment-II (Fall 2013) was conducted in 2015...

BACKGROUND: Cervical cancer is the fourth leading cause of cancer death in women, with 85% of cases and deaths occurring in developing countries. While organized screening programs have reduced cervical cancer incidence in high-income countries through detection and treatment of precancerous lesions, the implementation of organized screening has not been effective in low-resource settings due to lack of infrastructure and limited budgets. Our objective was to estimate the cost of comprehensive primary and secondary cervical cancer prevention in low- and middle-income countries...

To enable rational multi-epitope vaccine and diagnostic antigen design, it is imperative to delineate complete IgG-epitome of the protein. Here, we describe results of IgG-epitome decoding of three proteins from high-risk (HR-) oncogenic human papillomavirus type 58 (HPV58). To reveal their entire epitomes, employing peptide biosynthetic approach, 30 precise linear B-cell epitopes (BCEs) were mapped on E6, E7 and L1 proteins using rabbits antisera to the respective recombinant proteins. Using sequence alignment based on BCE minimal motif, the specificity and conservativeness of each mapped BCE were delineated mainly among known HR-HPVs, including finding 3 broadly antibody cross-reactive BCEs of L1 that each covers almost all HR-HPVs...

The objective of this study was to examine correlates of human papillomavirus (HPV) vaccine use according to Advisory Committee on Immunization Practices (ACIP)'s recommendations among US adolescent girls. We used National Immunization Survey of Teens 2013 data. Based on provider-verified (n = 9403) information, 57.3, 39.1 and 19.0 % of adolescent girls, initiated, completed and completed the HPV vaccine according to ACIP's recommendation (by age 12), respectively. Hispanic race/ethnicity, a physician recommendation for HPV vaccine and ≥1 influenza vaccine in the past 3 years were all associated with a higher likelihood of compliance with ACIP's recommendation...

HPV-associated head and neck squamous cell carcinoma (HNSCC), more specifically the incidence of oropharyngeal cancer, is dramatically increasing in industrialized countries. According to what has been learned from anogenital vaccination programs, there are reasons to believe that current human papillomavirus (HPV) vaccinations may be potentially effective also against HNSCC. However, before specific results on HNSCC are available, one must keep in mind that carcinogenesis in the head and neck region may differ from that of the anogenital tract...

BACKGROUND: The link between human papillomavirus (HPV) and anogenital cancers is well established in the literature. Many states have passed laws requiring funding for HPV education or vaccination. Mandatory HPV vaccination policies have been considered and passed in several states; yet their effectiveness has not been evaluated. This study sought to assess the impact of Virginia's HPV vaccine mandate for school-entry on HPV vaccine uptake among females aged 13-17 years. METHODS: Data from the National Immunization Survey-Teen for the 2008-2012 period were used, and 3,203 adolescent females were included in the analysis...
